NEW DEVELOPMENT
•
What is second generation organic?
•
•
provides corrosion control.
provides scale and fouling control.
•
Low phosphorus ! = kinder to environment
Utilize new chemistry 1
•
“Low ‘P’ phosphonate”
– Has lower P content, meaning low discharge impact
– Very strong corrosion inhibition.
– Is compatible with oxidizing biocides.

BCA “Biodegradable Carboxylic Antiscalant”
– Is biodegradable, traditional polycarboxylates are not.
– Is selected for long retention systems (re-use of blow

The economic value of lower corrosion rates
1. Total cost of operation:
A $ 10 MM plant , 5 mpy corrosion,
cost of corrosion = $ 500.000/year.
If corrosion is reduced to 1 mpy:
cost of corrosion = $ 250.000/year.
Cost of ownership savings = $ 250.000/year.
2. Fouling control is important because:
Fouling and corrosion are related, specifically, under deposit

The future in Water
Treatment
“No Chemicals!” (For
biocides)
Ultrasonic – a new discovery…
•
1996: Initial research & patent for the
application of ultrasound in medical research.
•
1997: Discovery that ultrasound controlled
growth of algae and bacteria in water
systems.
•
2002: Ashland further developed this
innovative technology leading to new patents.
•
Today: Award winning technology with over
•
500 Sonoxide units installed.
Recognized as an alternative to biocides.
Biofilms reduces efficiency & cost money…
Biofilm drastically reduces heat transfer
•
results in higher energy costs
reduction of thermal transmission coefficient
